Once they start to eat meaningful preys (no longer feeding on pinkies) they put on weight relatively fast which is why after 25 grams I feed every 5 days, there is always a fine line between feeding enough and feeding too much (also many people don't feed their colubrids enough), I could feed them more and they would eat but I do not want my animals to grow too fast and more importantly too fat.
At my feeding rate my females reach 200 grams by their second's birthday which is pretty much on target.
